Clone - HDD Duplication

'Clone' creates a clone of a hard drive by copying its sector information.
Select 'Clone' on the left side of the screen to display the following screen.

Fast Clone

Fast Clone skips unused space for faster cloning.
It can clone to a smaller hard drive than the source.
Normally, you should use Fast Clone for cloning.

Exact Clone

Exact Clone copies all data on the hard drive. It is slower because it also copies unused space.
It cannot clone to a smaller hard drive than the source.

Select the source drive

Select the destination drive

Click the 'Start Clone' button to begin cloning.

![IMPORTANT] If the destination disk is larger than the source disk, UBR will not expand the partition size.
Expand the partition size using Windows' Disk Management function.

![WARNING] After cloning, the source and destination hard disks will have the same Disk ID.
Generally, hard disks with the same Disk ID cannot be active at the same time.
Therefore, be sure to unplug either the source or destination hard drive before booting the OS after cloning.
